SPECIFICATION forming part of Letters Patent No. 775,778, dated November22, 1904:.

Application filed August 31, 1904:. Serial No. 222,817. No modelJ To allw'wnt t may concern:

Be it known thatI, WILLIAM J N uiLsoN, a

lcitizen of the United States of America, re-

siding at l/Vilson, in the county of Allegheny and State ofPennsylvania, have invented certain new and useful Improvements inMiners Cars, of which the following is a specification, reference beinghad therein to the accompanying drawings.

This invention has relation to mining-cars, and more particularly to thefastening' means of the end-gates thereof; and the object of thisinvention is to provide novel means for locking the end-gates ofmining-cars and for automatically releasing the same when they havereached a predetermined point.

Another object of this invention is to provide a lock for the gates ofmining-cars which will be extremely simple in construction, strong anddurable,.and comparatively inexpensive to manufacture, and aconstruction which will withstand the rough usages to which mining-carsare generally subjected.

Briefiy described, my invention consists of rotatably mounting a barupon the hinged end-gate of a car by bending the ends of said bar,whereby they will engage behind angleirons or clips carried by the sidesof said car and will hold the .gate of the car in a closed positionuntil the same is released. I further employ an automatic releasingmeans, which consists of a vertical reciprocating standard mountedadjacent to one side of the track, this standard being provided with anoutwardlyextending arm which is adapted to engage one of the bent endsof the rod and trip the same, whereby the gate of the car will bepermitted to swing. outwardly and release the load carried therein.

The above construction will be hereinafter more fully described and thenspecifically pointed out in the claims.

Referring to the drawings accompanying this application, Figure l is anend view of a mining-car, showing my improved lock and automaticreleasing means in connection therewith. Fig. 2 is a detail perspectiveView of the locking-rod. Fig. 3 is a top plan view of the clips orclasps employed 'upon the side of the car to engage the locking-rod.Fig. i is a side elevationof one of these clips. Fig. 5 is a detail viewof a portion of the hinged strips of the gate, showing the bearing forthe locking-bar; and Fig.' 6 is a horizontal sectional view taken on theline fu a' of Fig. 1 and showing a detail view of the standard.

Throughout the several views of the dravings accompanying thisapplication like reference characters designate corres ponding parts.

The reference character A indicates a mining-car of the ordinary andwell-known construction, which is provided with a hinged gate B, thisgate being hinged to a rod C, carried by the side strips D of the car.

The reference characters E E designate the hinged strips which arecarried by the gate, and these hinged strips are bent to form bearings ll for the locking-rod 2. This lockingrod lis clearlyshown in Fig. 2 ofthe drawings, and the ends thereof are bent rearwardly, as indicated at3, and downwardly, as indicated at 4. The downwardly-bent portion-t ofone end of the rod is bent outwardly, forming a lug 5;

Upon the sides of the car, near the end-gate thereof, and in horizontalalinement with the locking-bar 2 are secured the clips 6 6, the one endof these clips being provided with apertures 7 7, whereby they may besecured to the sides of the car, while the other end of said clips arebent at right angles, as indicated at 8 8, and in bending these endsthey are twisted to form an inclined surface 9. To lock the gate inengagement with the end of the car, the rod 2 is turned by the lug 5until the vertical portion 4.of. each end of the rod has engaged behindthe inclined faces of the clips 6 6, and the gate will be firmly andsecurely held in a closed position until the lug 5 has been struck torelease the vertical portion 4 from said clips. Y

The automatic releasing means for theunlocking of the gate B ascontemplated by me consists of a platform 10, which is mounted at oneside of the track and upon the side of the car which carries the lug 5of the lockingrod 2. Upon this platform is secured a standard 11, to thetop of which'is secured the spiral spring 12, and over said standard 11is placed a casing 14, to the top of which the upper end of the spiralspring is attached. The casing 14 is provided with an outwardlyextendingbar 15, having a curved upper face 15, this bar being arranged inhorizontal alinement with the lug 5, carried by the car, and should thelug 5 strike said bar the vertical portions 4 of said bar will be kickedor knocked out of engagement with the angular clips 6 6, carried by thesides of the car, and the load of the car be discharged, owing to thelock of the gate B being released.

I have provided the vertically-reciprocating casing 14, which is mountedover the standard 11, whereby the bar 15 can be raised, and the spring12 will return the same to its normal position. In some constructions ofmining-cars now used the locking means of the gate is placed lower thanthe top edge of the wheels which support the car, and in providing thevertical reciprocating casing 14 I have provided means whereby shouldthe wheels of the car strike the bar 15 the same will be raisedsufficiently by the wheels to permitthe same to pass and then bereturned for future engagement with the lug 5, carried by the car.

From the foregoing description it will be seen that when the locking-rodof the gate has been once secured behind the inclined faces9 of theclips 6 of the gate it will beimpossible for the same to becomedisengaged until the lug 5 has been kicked or knocked from engagementtherewith, and by providing the automatic releasing means I havedispensed with the trouble of employing a lever to accomplish this end,and my improved releasing means may be readily employed at such placesWhere it is desired to precipitate the load carried by the mining-carinto suitable conveyers or the like. It will also be noted that thevertically-reciprocating casing will be prevented from turning by reasonof the ribs arranged upon the standard and operating in guideways formedin the vertical reciprocating casing.

While I have herein shown the preferred manner of constructing myimproved cargate lock and automatic releasing means, I do not care tolimit myself to this specific construction, but may make such changes aswill be permitted by the appended claims.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. The combination with a mining-car having a hinged gate, of alocking-rod, said locking-rod havingbent ends,angular clips carried bythe sides of said cars and adapted to engage the ends of said rod, andmeans for automatically releasing said rod at predetermined locations,substantially as described.

2. The combination with a mining-car having a hinged gate, of a rodrotatably mounted upon said gate, said rod having bent ends, angularclips carried by the sides of said car and adapted to engage the ends ofsaid rod, and means for automatically releasing said rod atpredetermined locations, substantially as described.

3. The combination with a mining-car having a hinged gate, of a rodrotatably mounted upon saidgate` said rod having bent ends, angularclips carried by the sides of said car and adapted to engage the bentends of said rod, and automatic means for releasing said bent ends fromengagement with said clips at predetermined locations, and means forvertically reciprocating said bar, substantially as described.

4. The combination with a mining-car having a hinged gate, of a rodrotatably mounted upon said gate, clips carried by said gate and adaptedto receive the ends of said rod, and means for automatically releasingthe ends of said rod, substantially as described.

5. The combination with a mining-car having a hinged gate, of a rodrotatably mounted upon said gate, angular clips carried by the sides ofsaid car and adapted to engage the ends of said rod, a verticallyreciprocating bar mounted at the side of said car and adapted to engagethe end of said rod and release the same, and means whereby when saidbar is raised the same will be returned to its normal position.

In testimony whereof I affix my signature in the presence of twowitnesses.

WILLIAM J. NEILSON.
